The present invention "relates to nen7 and useful improvements in claspsfor tire chains, and is aA division of my formerapplication riledSeptember 2'th,1920, Serial No. 413,076, y i i y i i rlhe primary objectof the invention is the` provision o a clasp ior tire chains means oiwhich the chain ends `can be readily connected and drawn to theirdesiredtaut positions. y g

Another object of the invention is the provision of means for retaining`the chain ends in alignment ai'ter they have been secured together. Afurther object oli' the provision ol: a clasp comprising a levermechanism for tightening' the chain ends and securing' them together anda gripping means upon the oppositeends for holding' the clamp and chainends in alignment. i

A still further object of the invention is the provision oit a claspsuch as above referred to, which will be comparatively simple andinexpensive to manufacture, re-Y liable and el'licient in use, andreadily operated. y i

Wvith the above and other objects in View, the present invention residesin the novel features of construction, formations, combinationsandarrangements ot uparts to be hereinafter more particularlyydescribed, claimed, and illustrated inthe accompanying drawing9 forming"ya partiro'f the present application, and in which:

Figure l is a perspective `view showing the clasp in engjjagement withthe meeting` ends of a chain;

Figure 2 is a side view thereof before the chain is tightened;

Figure 3 is a plan view of one end oit' the device, and, t i

Figure 4 is an end View of that portion of the device shown in Figure 3.

`Referring; now tothe accompanying draw# it appertains to make and' sinvention is `the y the reeend of the chain.

bent rdownwardly'upon,.itseliias'at ll toi@ t of the chain. A spring,`l2`is secured as at 13 by riveting or the like to the end of the bar 8adjacent` the above described guide,

` `form a guide for receiving theopposite end` Whilethe Jfree extremityIof the spring` is i i bent as at lllaronnd the rear end of the guidepartly 'closing the same7 as shovvn in Figures?) and 1, and is then bentback-` Wardly upon itself as at l5 to `provide a` smooth edge againstwhich the chain rides While being forced into the before described guidemember. y

y in use, the device is cable for tire chains, but it is to be Under-Vstood that it may be employed for any other `purpose to which thevarious will. adapt themselves.

l'n applying the chain, theiclasp is held in the `position shown in.Figure 2 with the link in i hook terminal 9 through the/'desired Thebar 8 then i drawn painllel to the chain, n: shown in Figure l, and(thelguide is 'Forcedv downwardly past the" chain `which isreceivedbetween thelineinbers l() and llfin which posii `tion the clampis locked in ahgnmentwith they chain so as to preventthe chain fromtwistingr past the said springend' guide.`

` `It will. beseen that the portion l5 of the springvis bevelled `whichvpermits the in-` sertion ofthe spring' into the guide .menil'ier butprevents its isplacement" therefrom, f

Fronrrthe foregoing description, tal-:en in connection with theaccompanying drawing, it will be manifest that a clasp Jfor chains andthelilre isprovided, which ivlliiulfill` t all of the necessary`requirements ot such a device, and it should be understood in thisconnection,` that various minoiifchanges in the specific details ofconstruction can be resortedfto Within the scope of the appended claimsWithout departing 'from the spirit orl sacrilicing any of the advantagesof the invention.
